Mexico City (CNN)Mexico's biggest earthquake in more than three decades brought parts of the capital to its knees on Tuesday afternoon. But moments later, as the earth continued to tremble, many of Mexico City's residents stood up and mobilized.

When news emerged that an elementary school had collapsed, city residents and people from surrounding regions -- including some hit hardest by the quake -- traveled to the city's Coapa district en masse, bringing everything and every skill they could muster to help dig out those buried under the rubble. At least 273 people died in the 7.1-magnitude quake.
